Jay Walder, who heads the company that operates Citi Bike, says that he isn’t on board with a bill that would require it to make all its financial information public.

The legislation, sponsored by Councilman Ydanis Rodriguez, would release yearly data on whether the program is running at a deficit or profit, and how revenue is allocated.

“We put out a tremendous amount of financial information already,” Walder, the former chairman of the MTA, told Crain’s. “I think you can find an awful amount of that information on our Web site already. It is there and people can use it.”

Currently, Citi Bike releases its gross revenue on a monthly basis, but doesn’t share whether it is profitable.

The union repping Citi Bike workers said they support greater transparency.

“When Walder was with the MTA, he had no choice but to be transparent, so he should know better than to think he could withhold information like this when the city is bending over backwards to make his company a success,” said Earl Phillips, a secretary and treasurer at TWU Local 100.

Citi Bike said in a statement that it supports open data, but that some proprietary financial data should stay confidential.
